You've had one of those great moments in gaming history, the one where you did something you could probably never again duplicate, but no one was around to witness it. Now thousands can.

iBUYPOWER, maker of powerful gaming PCs, is launching a new line of video PCs, developed with the amateur videographer in mind. And to promote them, they're giving away one of their $1800 Video Pro systems - packed with an Intel Core 2 Quad Q9550 processor, ATI Radeon HD 4850 graphics card and 8 GB of DDR- 2 RAM, in a Gigabyte Poseidon gaming tower case - in their Favorite Gaming Moments YouTube Contest.

Just reenact your best moment, upload the video to Youtube any time before the end of August, and the winner will be selected from a group of ten finalists by the You Tube community in the second week of September. You've gotta have at least one Madden moment worth posting. Start the camera.
